Abstract
(EN)
It is possible to eliminate the problems of adsorption/separation efficiency and recovery efficiency of magnetic flocks in the conventional magnetic separation device and effectively remove the magnetic flocks contained in the raw water. In the magnetic separation device, a plurality of magnetic discs (36) are arranged so that they are substantially half under the raw water in a separation vessel (32). A water supply opening (44) for supplying the raw water as an upward flow is formed in the separation vessel (32) at the lower end of the separation vessel (32). Furthermore, immediately below each of the magnetic discs (36), a distribution member (46) is arranged to distribute the raw water supplied from the water supply opening (44) to rightward and leftward and the thickness direction of the magnetic disc (36). A pair of troughs (40) are arranged at both sides parallel to the rotation axis of the separation vessel (32) so that the processed water from which the magnetic flocks (F) have been removed from the raw water flows over.

La présente invention propose un dispositif de séparation magnétique qui permet d'éliminer les problèmes de rendement d'adsorption/séparation et de récupération de flocs magnétiques présenté par un dispositif de séparation magnétique classique et d'éliminer efficacement les flocs magnétiques contenus dans l'eau brute. Dans le dispositif de séparation magnétique proposé, plusieurs disques magnétiques (36) sont disposés pour être sensiblement à moitié immergés dans l'eau brute contenue dans un récipient de séparation (32). Une ouverture (44) d'alimentation en eau brute sous forme de courant vers le haut est formée à l'extrémité inférieure du récipient de séparation (32). De plus, immédiatement au-dessous de chacun des disques magnétiques (36), un élément de distribution (46) est disposé pour distribuer l'eau brute amenée par l'ouverture (44) d'alimentation en eau vers la droite, vers la gauche et sur la tranche du disque magnétique (36). Deux réceptacles (40) sont disposés sur les deux côtés parallèlement à l'axe de rotation du récipient de séparation (32) pour recevoir l'eau traitée constituée par l'eau brute dont les flocs magnétiques (F) ont été retirés.

 従来の磁気分離装置がかかえる磁性フロックの吸着分離効率、及び回収効率の問題を解消し、原水中に含有する磁性フロックを高性能に除去することを可能にする。  磁気分離装置に、複数枚の磁気ディスク(36)を分離槽(32)の原水中に略半水没されるように配置する。分離槽(32)の下端に、原水を分離槽(32)内に上向流として給水する給水口(44)を形成する。さらに、それぞれの磁気ディスク(36)の真下に、給水口(44)から給水された原水を磁気ディスク(36)面の左右方向及び厚み方向に分流する分流部材(46)を配設する。分離槽(32)の回転軸と平行な両側に、原水中の磁性フロック(F)が除去された処理水が越流する一対のトラフ(40)を設ける。
